In order to test the viability of oil sands aquatic reclamation techniques, yellow perch (Perca flavescens) were stocked into three experimental ponds. Pond substrates consisted of either oil sands fine tailings or clay and lean oil sands deposited by the mining operations. Yellow perch were stocked immediately postspawning and subsamples were sacrificed at 5 and 11 months to measure indicators of energy storage and utilization. These indicators included survival, age, spawning periodicity, condition factor, gonad size, fecundity, and liver size. Indicators generally showed patterns consistent with improved energy storage and utilization in the experimental pond yellow perch as compared with yellow perch in the lake from which the stocked fish originated. This was evidenced by increased gonad size, condition factor, and liver size and the disappearance of spawning periodicity. The patterns observed in experimental ponds suggest improved resource availability and (or) reduced intra- and interspecific competition. Yellow perch physiological indicators were also compared with those measured at several remote natural lakes in the area. Fisheries parameters measured in yellow perch from the experimental ponds generally fell within the range of those found in natural lakes.

Adult yellow perch (Perca flavescens) were stocked into experimental ponds designed to emulate possible aquatic reclamation alternatives of the oil sands mining industry. After 5 and 11 months, mixed-function oxygenase (MFO) activity, liver conjugation enzymes, bile polycyclic aromatic hydrocarbon (PAH) equivalents, and plasma sex steroids were measured. Liver MFO activity and bile PAH equivalent concentration were closely correlated and showed the highest levels in the experimental ponds but also demonstrated a gradient of exposure among reference locations. Levels of steroid hormones in fall-captured fish did not show major differences among sites. However, during winter, yellow perch from three sites, including the experimental ponds, showed low levels of sex steroids in both males and females. Multivariate regressions showed no relationship between steroid hormone concentrations and gonad size or fecundity. Similarly, steroid hormones did not parallel the gradient of exposure as measured by MFO and bile PAH metabolites. Gonad size and fecundity also were not directly correlated with the gradient of exposure observed in this study. Although MFO activity and bile PAH equivalents were good indicators of exposure to oil sands related waters, they were not predictive of physiological endpoints, suggesting that the latter were influenced primarily by ecological and not by chemical factors.

Increasing demand for diluted bitumen (dilbit) has led to the development of the Alberta oil sands industry and the expansion of current and future transcontinental pipelines. However, the growth of oil transportation has led to public concern about the effects of potential dilbit spills to aquatic ecosystems. Although the toxic effects of crude oils through exposure to polycyclic aromatic hydrocarbons (PAH) are well characterized, little is known about the toxic effects of dilbit because of the variable proportions of diluent added to bitumen. Here we assessed the toxicity of the two most transported dilbits in Canada, Access Western Blend (AWB) and Cold Lake Blend (CLB) to developing yellow perch (Perca flavescens), a species distributed throughout North America. Embryos were exposed to dilbit until hatch, or up to 16 days, using a static daily renewal treatment regime of water accommodated fractions (WAF) and chemically-enhanced water accommodated fractions (CEWAF) of dilbit at total PAH (TPAH) concentration ranges of 0.02 to 10.7 μg/L and 0.21 to 20.4 μg/L TPAH, respectively. Results show that with increased TPAH concentration, the frequency of hatched embryos with developmental malformations increased proportionally. Expression of genes associated with phase I and II detoxification, cellular stress, and xenobiotic metabolism were altered in higher TPAH concentrations. This is the first study assessing the toxicity of both AWB and CLB dilbits on wild-sourced fish. With recent approvals of pipelines in North America, these biomarkers will assist risk assessments and monitoring of Canadian ecosystems should a pipeline spill occur.

Laboratory-based bioassays were conducted to determine concentrations of sodium-sulfate type salinities that limit the hatching success of several fish species. Survival to hatching (SH) was significantly lower (P < 0.05) in sodium-sulfate type waters from Devils Lake, North Dakota, of ≥ 2400 mg/L total dissolved solids (TDS) than in fresh water of 200 mg/L. In waters of 200, 1150, 2400, 4250, and 6350 mg/L TDS, walleye (Stizostedion vitreum) SH was 41, 38, 7, 1, and 0%; northern pike (Esox lucius) SH was 92, 68, 33, 2, and 0%; yellow perch (Perca flavescens) SH was 88, 70, 73, 0, and 0%; white sucker (Catostomus commersoni) SH was 87, 95, 66, 0, and 0%; common carp (Cyprinus carpio) SH was 71, 69, 49, 63, and 25%.

Little is known about the animals that occupy naturally acidic habitats. To better understand the physiological state of animals from temperate, naturally acidic systems, we compared metabolite stores and meristics of two yellow perch (Perca flavescens) populations in northern Wisconsin. One population originated from a naturally acidic, dystrophic lake (Acid-Lake-Perch, ALP) and had previously been shown to have enhanced tolerance to low pH. The second population came from two nearby interconnected circumneutral, mesotrophic lakes (Neutral-Lake-Perch, NLP). Perch were collected throughout the year to account for seasonal effects and to discern whether patterns of metabolite utilization differed between populations. ALP had smaller livers containing less glycogen and greater muscle glycogen content than NLP. The ALP also had significantly greater liver and visceral lipid contents, and females from this population committed a greater fraction of their body mass to egg production. We interpret these results as indicative of physiological divergence at the population level in yellow perch. These results are discussed as possible products of H+ -driven changes in metabolism and as possible products of different life history strategies between populations. Our results also show that perch living in acidic, dystrophic Wharton Lake are not acid stressed.

In an investigation of the commercial fishery of Red Lakes, Minnesota, for the 46-yr period 1930–75, catch statistics were analyzed, and the dynamics of the perch and walleye populations were examined. Mean annual yields of walleye for two statistical periods, 1930–53 and 1954–75, were 309,900 and 245,100 kg, respectively for walleyes, and 96,400 and 109,500 kg for perch. Annual abundance (CPE based on average catches per day per 5-net units of gill nets) varied from 3.8 to 64.6 kg for walleye, and from 2.5 to 34.4 kg for perch. Causes of fluctuations in harvestable stock were directly related to strength of year-classes and to growth rate during the season of capture. Year-class strength was not related to the abundance of parent stock or of potential predators. The respective strengths of year-classes of perch and walleye in the same year were positively correlated (r = 0.859, P < 0.01), and are directly related to climatic factors. Growth rate of walleye in different calendar years varied from +30.7 to −42.2% of mean growth, and that of perch from +13.4 to −8.6% (1941–56). Growing season began in mid-June and was almost over by September 1. Walleye yield could be enhanced by starting harvest July 1 instead of early June. Perch yield could be improved by harvesting small perch. Key words: Percidae, Perca, population dynamics, Stizostedion, long-term yield

Zebra mussels (Dreissena polymorpha) in enclosures located in an experimental pond adjacent to Lake St. Clair, Michigan, increased sedimentation rate but had relatively minor effects on percent organic matter and percent nitrogen content of sediment. In contrast, sediment from Lake St. Clair adjacent to zebra mussels was significantly higher in carbon than that 0.5 m away. Zebra mussels increase the nutritional value of surficial sediment and provide greater structural heterogeneity, which is probably more important in causing change among zoobenthos. Zoobenthos and yellow perch (Perca flavescens) diet were dominated by dipteran larvae and leeches. Zoobenthos was significantly different between enclosures with and without zebra mussels. Treatments with zebra mussels had significantly more oligochaetes and tended to have more crustaceans (isopods and amphipods). In June, yellow perch without zebra mussels consumed significantly more zooplankton, and those with mussels had more crustaceans in their diet. Zooplankton density was greater in treatments without zebra mussels. Yellow perch with zebra mussels grew significantly more than those without mussels. Zebra mussels in the enclosures neither reproduced nor were eaten by yellow perch; hence. the observed growth differences were due to indirect effects involving zebra mussel induced changes in benthic structure and biota.
